Are there any ways to get any extra memory on the phone, I already have a memory card in it but need to have more memory for my music player. Or can it automatically be saved to some sort of cloud?
Both OneDrive and Google Drive support free and paid storage options. You can try a USB-C flash drive to see if it recognizes it. You can get a bigger SD card and move current content on to it. I think S9 support up to 1TB cards.
Samsung has cloud storage too but it very limited since they move to OneDrive. You have to setup backups using a service or your choice. Sure they will be sued if they try to do it automatically for users
